Social work field instructors are responsible for the gatekeeping function of evaluating student performance and determining practice readiness. Yet little empirical literature elucidates how field instructors of graduating BSW students judge competence, suitability, or readiness for practice. This qualitative study reports findings from 6 focus groups attended by 28 experienced BSW field instructors aimed at (a) exploring criteria used to judge student readiness for entry-level practice and (b) examining differences in expectations based on micro and macro placements. Two capacities emerged as being paramount in supporting the development of practice skills, personal attributes, and areas of practice in both micro and macro placements: conceptualization and self-reflection. Implications for evaluating student competence and supporting student learning in the field are discussed.
